Abstract: A test stand for internal combustion motors, is constructed to provide an optional test load for the motor. The motor is connected to an axle by a connecting member at one end of the axle mounted in the test stand. The opposite end of the axle is connected to a brake rotor having brake members in the form of ropes or strips affixed to its periphery. When the brake rotor with its brake members is rotated, friction arises between the brake members and the ambient air or gas. This friction provides the desired test load for the motor via the brake rotor and the axle.
